FORM FOR PLASTIC BURIAL VAULTS.

Specification of Letters Patent.

Patented Mar. 14, 1922.

Application filed March 24, 1921.. Serial No. 455,358.

' cover, the base extending into the cover and supporting the casket'within the cover and the cover seating on a flange at the bottom of the base.

The object of the inventi'on is to provide a novel form or mold which shall be'collapsiblc and adjustable and by which burial vaults may be manufactured rapidly and accurately, danger of injury to the vault by cracking ortearing when removed from the form being eliminated.

The invention consists inan inner form member for the covercomposed of four overlapping and adjustable parts adapted to be .rigidly secured together anda knock-down ,louter form member, an embodiment of the same being illustrated in the drawings, in

which drawings- Figure l is aside elevational view ofthe assembled exterior form for the cover or hell v of the vault; Fig. 2 an end elevational view of the same; Fig. 8 a plan view of the inner form member of the cover in assembled position; Fig. 4- a side elevational view of the inner form member; Fig. 5 an end view of the inner form member; Fig. 6 a side elevational View of the upper member of the base form; Fig. 7 an end view of the same; Fig. 8 a side elevational view of the lower member of the base form and Fig. 9 an end view of the same.

Referring to the drawings the cover of the vault is made in the form or mold illustrated in Figs. 1 to 5, and the base in the form or mold illustrated in Figs. 6 to 9.

The inner member of the cover form comprises four sections 1, 2, 3 and 4, preferably formed of metal. Each section consists of two vertical walls 5 and 6 with a top portion 7 integral with or connected to the vertical walls, the top portion being curved transversely, and a flange 2 projecting laterally from the lower edge of the walls 5 and .a wooden .frame 15.

6. Cleats 9 extend upwardly at suitable points along the outer edge of the flange and serve as guides for the exterior form member. The four sections are adapted to overlap when assembledthat is, section 1 overlaps sections 2 and 3, section 2 overlaps sections 3 and 4 and section 3 overlaps section 4. Apertures 10 are formed in the portions of the sections adapted to overlap and when the sections are adjusted to the size of vault to be constructed screws 11 are inserted through registering apertures and engaged in brace 12 secured to uprights 13 secured to planks 14, the brace, uprights and planks being of wood. The sections are placed on The braclng structure within the form just described rigidly supports the form and prevents its collapse by the weight of the concrete when poured on the form. The exposed apertures 10 not in use are suitably plugged to prevent the con crete' from passing through the same. I

The exterior form member comprises two side plates 16 of metal conforming to the desired shape of the side walls of the cover, and two end plates or gates 17 also conforming to) the desired shape of the ends of the cover. Preferably the top of the cover is convex and accordingly the upper edge 18 of each gate is rounded to conform to the dcsiredcontour of'the' cover. The side plates at their lower edges abut the cleats 9 on the side portions of flanges 8 and in like manner the lower edges of gates 17 abut the cleats?) on the end portions of flanges 8.

Rods 19 are inserted through apertures in the extremities of side plates 16 and wing nuts 20 are tightened on the rods to hold the plates in parallel relation, the outer faces of the end gates abutting the said rods. Bracing bars 21 are secured to the side plates to make them rigid and thereby enable thin m a t-erial for the plates to be used. The upper and lower edges of each side plate are arched over as at 22 and 22 to stiffen the plate along said edges and bracing bars 23 are extended upwardly through apertures in the arched portions 22. A tie rod 24 with wing nut 25 is inserted through apertures in the upper ends of said bars 23 to afford additional bracing of the side plates.

Each end gate is formed with a transverse outwardly flared portion 26 which form on the ends of the completed cover a transverse shoulder or rib extending entirely across the end of the cover under which shoulders a rope or chain is engaged for raising the cover first out of the mold and thereafter in handling the .cover.

When the cover form is assembled as above described the cement mixture is poured in between the inner and outer membersof the form and as the upper edge of the side plates is reached the mixture ap plied is thicker in consistency so that it will pile up above those sides and between the upper portionsof the end plates and enable the operator to smooth oil the top surface oi 7 33 of thetrough :32. The plastic material is poured onto the bottom section and ,tamped inQbetWeen the Walls of the shell and the side Walls of the bottom section and smoothed off with a suitable tool ,guided by the .upper edge of the shell. The trough 32 forms the flange about the base npon which the lower face otthe cover seats when installed. v f

. p is apparent fromthe foregoing thatthe mold is most simple in construction and readily set up and taken down; When a coverhas been poured it is allowed .to set in the mold and when fully set, the tie rods are removed and the side plates andend gates are removed and the cover. readily lifted off the inner form member. The exte rior form is again assembled and anothercover s poured with a mlnimum of labor.

The guide cleats 9 on the-inner member of the cover form center the exterior member or the cover form so that no adjustment of either member is necessary to properly center the same.

hat We claim is:

'1. A form for the uses and purposes describedcomprising an inner and anexterior member, the inner member being composed oi i'our adjustably overlapping sections, a reinforcing frame Within vthe inner member to which the overlapping sections are removably secured, and guides on the inner member adapted to be engaged by the eXterior member for centering the two members.

2. A form .for the uses and purposes described comprising an inner and an exterior member, the inner member being composed of four adjustably overlapping sections, .a reinforcing "frame Wltlllll the inner member to which ,the overlapping sections ,are removably secured,the exterior member being composed oi? two sidewalls and, two :end Walls'and means on the inner member to center the e Xt-erioremember with respect :to the inner member: y r p A form for the uses and purposes described comprising an inner and an exterior member, the inner member being Composed of a plurality oii overlapping sections, means to reinforce and secure the said sections in verlapped positiolnand the exterior member having separable'end and side members and means to tie them together, each end inemberhaving its upper portion extended abos 'e the side members and its upper edge ,eontorming in outline to the desired eon tour for the top of the articleto be "made in the form, and each end member having an outwardly flared lJOlillOIl-lllltS upper part and extending laterally of the same.

In. witness whereof we have hereunto sub scribed our names this 22nd day of March,
